ELNA or THURE or IDA Frisk - looking for information

My Great - great grandmother was Elna Frisk - married to a Gustaf Hanson.I can not seem to find much information on Elna or her parents.I'm not even sure if Thure and Ida Frisk are her parents.They are of Swedish immigrants. Just started my family tree search - can't get beyond gg grandmother - If anyone has any information I would be so grateful!Thank you!
